NFSv4.2: Serialise O_DIRECT i/o and clone range
[ Upstream commit c80ebeba1198eac8811ab0dba36ecc13d51e4438 ]
Ensure that all O_DIRECT reads and writes complete before cloning a file
range, so that both the source and destination are up to date.
Fixes: a5864c999de6 ("NFS: Do not serialise O_DIRECT reads and writes")
